Another key point of this work is that we combine the IMC architecture for higher energy efficiency. [1]}, [2]} also uses in-memory computing and [3]}, [4]} uses approximate computation that is also an analog domain computation for lower power consumption. [5]} is the full digital design counterpart for a similar application. Compared to these state-of-the-art works, this work has higher energy efficiency and on-chip training capability for customization.
